ABSTRACT

Systems, methods, and computer program products for transmitting data between devices are disclosed. A device may utilize a standardized communication system (“SCS”) to transmit data directly between devices including an SCS. The SCS may discover available devices. The SCS may determine available transmission paths between a first device and a second device. The SCS may select a transmission path between the first device and the second device, and the SCS may transmit data from the first device to the second device using a standardized communication protocol (“SCP”). The first device may transmit a message to the second device. The first device may edit the message after the transmitting. The second device may delete the original message. The second device may store the edited message.

CROSS-REFERENCE TO RELATED APPLICATIONS

This application claims priority to U.S. Provisional Application Ser. No. 62/023,059 entitled “SYSTEMS AND METHODS FOR MESSAGE EDITING” and filed on Jul. 10, 2014 which is incorporated herein by reference in its entirety.

FIELD

The present disclosure generally relates to transmitting data, and more particularly to systems and methods for editing data transmitted between devices.

BACKGROUND

Communication between devices is typically performed over a network, such as the internet or a local area network. However, networks may not always be available for communication between devices and additionally may expose communications to security breaches on the network. Devices enabled with Bluetooth® may communicate directly. However, Bluetooth® enabled devices must be within a limited range, and communication speeds may be relatively slow.

Many devices may include a wireless chip. Manufacturers may create specialized wireless chips which enable communication between devices containing compatible wireless chips. However, such devices may be unable to communicate with other devices containing chips manufactured by other manufacturers.

Many devices may allow users to transmit data, such as text messages to other users. Typically, once the text message is delivered to a device, the text message is saved locally on the device. It may not be possible for a user to edit or delete a message which was previously sent to another device.

SUMMARY

Systems, methods, and computer-readable media for transmitting data are disclosed. In various embodiments, a method may include implementing a standardized communications protocol (“SCP”) on a first device. The method may further include discovering a second device. The method may further include selecting a transmission path. The method may further include transmitting a message to the second device.

In various embodiments, a method may comprise receiving, by a first device comprising a processor for communicating with a second device, a datagram from a second device. The method may further comprise identifying a standardized communication protocol (“SCP”) header in the datagram. The method may further comprise transmitting, by the processor, a list of available transmission paths to the second device. The method may further comprise receiving, by the processor, a message from the second device over at least one transmission path in the list of available transmission paths.

In various embodiments, a method may comprise receiving, by a messaging server, an original message from a first device; receiving, by the messaging server, a request for new data from a second device; transmitting, by the messaging server, the original message to the second device; receiving, by the messaging server, an edited message; deleting, by the messaging server, the original message from the second device; and transmitting, by the messaging server the edited message to the second device.

DETAILED DESCRIPTION

The detailed description of exemplary embodiments herein makes reference to the accompanying drawings and pictures, which show various embodiments by way of illustration. While these various embodiments are described in sufficient detail to enable those skilled in the art to practice the disclosure, it should be understood that other embodiments may be realized and that logical and mechanical changes may be made without departing from the spirit and scope of the disclosure. Thus, the detailed description herein is presented for purposes of illustration only and not of limitation. For example, the steps recited in any of the method or process descriptions may be executed in any order and are not limited to the order presented. Moreover, any of the functions or steps may be outsourced to or performed by one or more third parties. Furthermore, any reference to singular includes plural embodiments, and any reference to more than one component may include a singular embodiment.

Systems, methods and computer program products are provided. In the detailed description herein, references to “various embodiments,” “one embodiment,” “an embodiment,” “an example embodiment,” etc., indicate that the embodiment described may include a particular feature, structure, or characteristic, but every embodiment may not necessarily include the particular feature, structure, or characteristic. Moreover, such phrases are not necessarily referring to the same embodiment. Further, when a particular feature, structure, or characteristic is described in connection with an embodiment, it is submitted that it is within the knowledge of one skilled in the art to effect such feature, structure, or characteristic in connection with other embodiments whether or not explicitly described. After reading the description, it will be apparent to one skilled in the relevant art(s) how to implement the disclosure in alternative embodiments.

Systems and methods are disclosed herein for peer to peer communication between communication devices. As used herein, a “communication device” may refer to any device capable of communication with another device. For, example and without limitation, a communication device may refer to a smartphone, PDA, laptop, desktop computer, portable phone, GPS device, car navigation system, wireless printers, or any other device.

The systems and methods disclosed herein may enable communication between devices without connection to the Internet or other networks. A standardized communication system (“SCS”) may be installed on a device. The SCS may comprise any combination of hardware and/or software. The SCS may utilize existing physical components of the device, such as 802.11 wireless chips and Bluetooth® systems in order to communicate with other devices. The SCS may be suitable for any communication protocol, such as IP, TCP/UDP, Bluetooth®, raw Manchester encoding, and any other form of wireless communication.

The SCS may allow communication between devices of varying types and platforms. Additionally, as communication may be directly between devices without transmitting data across a network, communication may be available when networks are unavailable, and communications may be protected from eavesdroppers on a network. Furthermore, direct communication between devices may avoid data charges on cellular data plans.

Referring to FIG. 1, a system 100 for transmitting messages is illustrated according to various embodiments. A first device 110 comprising an SCS 112 and a second device 120 comprising an SCS 122 are illustrated according to various embodiments. In various embodiments, SCS 112 and SCS 122 may be aftermarket software programs installed on first device 110 and second device 120. However, in various embodiments, SCS 112 and SCS 122 may be embedded into a chip, such as an 802.11 wireless chip, in first device 110 and/or second device 120.

In various embodiments, the SCS may implement a standardized communication protocol (“SCP”) on a device. SCP may attach an SCP header 152 to a packet in order to identify a datagram 150 as an SCP datagram. First device 110 may communicate with second device 120 via SCP. The SCS may recognize the SCP header and may follow the SCP. The SCP may define the ability for devices to discover one another, to request the transfer of raw data, to transmit confirmations on receipt of data, and to perform any other steps involved with transmitting data.

In various embodiments, the SCS may be implemented at the network layer in the Open Systems Interconnection (“OSI”) model (or the Internet layer in the TCP/IP model). Regardless of the protocol being used at the transport layer (e.g. TCP, UDP, SCTP, DCCP), the SCP header may allow devices comprising an SCS to communicate via SCP.

In various embodiments, at least one of first device 110 and second device 120 may comprise a smartphone. However, in various embodiments, first device 110 and second device 120 may comprise any type of device capable of transmitting and/or receiving data.

Referring to FIG. 2, a process 200 for transmitting data between devices is illustrated according to various embodiments. In various embodiments, a first user may wish to transmit data from first device 110 to second device 120. The data may comprise any type of data, such as a text message, image, video, text document, or any other type of file.

First device 110 may discover available devices (step 210). First device 110 may attempt to discover other devices by a variety of methods. In various embodiments, first device 110 may discover other devices via a camera or other optical device. In various embodiments, second device 120 may display a symbol, such as a QR-code, a barcode, or text. The symbol may comprise identifying characteristics about second device 120. For example, in various embodiments the identifying characteristics may comprise at least one of a device name, an IP address of the device, an owner name, an endpoint of the device, and the available transport layers on the device. First device 110 may scan the symbol using a camera. First device 110 may obtain the identifying characteristics from the symbol and use the identifying characteristics in order to transmit data to second device 120.

In various embodiments, the SCS on first device 110 may search for other devices using a wireless chip in first device 110. Devices comprising an SCS may transmit a broadcast message. The broadcast message may comprise the identifying characteristics of the device. In various embodiments, first device 110 may be within transmission range of second device 120. The transmission range may depend on the specific type of wireless chips in first device 110 and second device 120. However, in various embodiments, the transmission range may be up to about 200 feet-300 feet. The SCS may open a socket on first device 110 to listen for broadcast messages. The broadcast message may be sent by a variety of hardware. For example, the broadcast message may be transmitted via an 802.11 wireless chip, Bluetooth® chip, or NFC.

In various embodiments, first device 110 and second device 120 may not be within transmission range of each other. However, an intermediary device, such as a smartphone equipped with hotspot technology, may be within transmission range of first device 110. First device 110 may search for available devices by transmitting a message to intermediary device, instructing intermediary device to look for available devices. Intermediary device may receive a broadcast message from second device 120, and intermediary device may transmit the broadcast message to first device 110. Thus, first device 110 may discover second device 120 without connecting to the internet or a cellular network even though first device 110 may not be within transmission range of second device 120. In various embodiments, any number of intermediary devices may be daisy-chained, such that first device 110 may discover second device 120 from miles apart by transmitting data via a series of intermediary devices.

First device 110 may display a list of all discovered devices to the user. The user may select second device 120 in order to transmit data to second device 120. The user may select a file or message to be transmitted to second device 120.

The SCS 112 on first device 110 may determine the transmission hardware to utilize for the transmission (step 220). In various embodiments, first device 110 and second device 120 may each have only one type of transmission hardware, such as an 802.11 wireless chip, and the SCS 112 may thus select the 802.11 wireless chip to transmit the data. However, in various embodiments, multiple transmission paths may be available between first device 110 and second device 120. For example, first device 110 and second device 120 may each comprise an 802.11 wireless chip and a Bluetooth® chip. In various embodiments, the SCS 112 may determine the fastest transmission path, and may select the fastest transmission path to transmit the data. In various embodiments, the transmission path may be selected by default settings. For example, SCS 112 may always select an 802.11 wireless path for transmission when available, and if the 802.11 wireless path is not available, SCS 112 may select a Bluetooth® path. However, in various embodiments, the SCS 112 on first device 110 may transmit a speed test message to second device 120 via each available transmission path, and the SCS 112 may select the fastest transmission path based on the speed test results.

In various embodiments, the SCS 112 may instruct first device 110 to send the data to second device 120 via multiple transmission paths. A message may be divided into multiple packets. SCS 112 may analyze the available transmissions paths, and send the message over multiple transmission paths in order to expedite transmission of the entire message. For example, SCS 112 may determine that the fastest method of transmitting the message may be to transmit 90% of the packets via an 802.11 wireless path, and 10% of the packets over a Bluetooth® path. SCS 112 may attach an SCP header to each packet being transmitted to second device 120, whether via 802.11 wireless or Bluetooth®. Thus, SCS 122 on second device 120 may recognize the packets as being received by SCP, and SCS 122 may reassemble the packets in order to recreate the entire message. In various embodiments, SCS 112 may analyze all transmission paths available, including but not limited to multiple 802.11 wireless chips, Bluetooth® chips, NFC, PDQ, or any other transmission paths in order to select the fastest transmission method. The SCS on first device 110 may initiate a file send protocol and transmit the data to second device 120 (step 230).

In various embodiments, first device 110 and second device 120 may be connected to the same local network. First device 110 may transmit a link, such as a QR-code, over a cellular network or the local network to second device 120. In various embodiments, the link may comprise 10 kb or less of data. Second device 120 may use the link to request or accept a file transfer. First device 110 may transmit a file over the local network. In various embodiments, the file may be transferred using TCP/IP directly over the local network.

In various embodiments, second device 120 may have access to an internet connection. First device 110 may transmit a link over a cellular transmission path to second device 120, and second device 120 may use the link to download a file stored on the cloud and/or on a server over the internet. In various embodiments, second device 120 may download the file using TCP/IP.

In various embodiments, first device 110 may sync its contents with a cloud database. In various embodiments, first device 110 may comprise an SCS folder, and only files stored in the SCS folder may be synced with the database. First device 110 may transmit a link over a cellular transmission path to second device 120 identifying a file stored on the database. In various embodiments, second device 120 may not have access to an 802.11 wireless network at the time second device 120 receives the link. Second device 120 may use the link to access the file whenever second device 120 gains access to an 802.11 wireless network in order to prevent cellular data charges. In various embodiments, second device 120 may use the link to access the file over the cellular network. In various embodiments, second device 120 may stream all or part of the file over either the cellular network or an 802.11 wireless network.

In various embodiments, first device 110 may share an online folder with second device 120. First device 110 may indicate that second device 120 may have access to an online folder. First device 110 may sync with the online folder to upload files stored on first device 110 to the online folder. Second device 120 may sync with the online folder to download files stored in the online folder to second device 120.

Referring to FIG. 3, a process 300 for a file send protocol is illustrated according to various embodiments. First device 110 may transmit a request to establish a connection with second device 120 (step 310). In various embodiments the connection may comprise a TCP connection. However, in various embodiments, the connection may comprise any type of connection for transmitting data between devices. Second device 120 may accept the connection request (step 320). In various embodiments, the connection may be between secure sockets on first device 110 and second device 120.

In various embodiments, first device 110 may transmit a message comprising a cypher book to second device 120 (step 330). The cypher book may comprise a list of one-time cyphers, and may allow second device 120 to decrypt data sent to second device 120 over the secure socket connection using one time cyphers. In various embodiments, first device 110 may encrypt the message comprising the cypher book using known encryption methods, such as Advanced Encryption Standard (“AES”) or RSA encryption. However, subsequent messages during the transfer session may be encrypted using the one-time cyphers contained in the cypher book. The messages encrypted using the one-time cyphers may be encrypted and decrypted using significantly less processing power and time than messages encrypted with AES or RSA. Additionally, the messages sent using the one-time cyphers may be indecipherable to parties not containing the cypher book.

First device 110 may send a file transfer request (step 340). For an example of a file transfer request, refer to FIG. 5. Second device 120 may accept the file transfer request (step 350). In response to second device 120 accepting the file transfer request, first device 110 may break the file into segments, and begin transmitting the segments to second device 120 (step 360). After first device 110 has transmitted all segments of the file, first device 110 may wait for confirmation that second device 120 has received all segments. Second device 120 may transmit a confirmation message to first device 110 indicating that all segments have been received (step 370). Second device 120 may decrypt and reassemble the segments according to SCP in order to recreate the file (step 380).

Referring to FIG. 4, an example of a discovery protocol 400 is illustrated according to various embodiments. Discovery protocol 400 may be implemented on the transport layer using TCP/UDP. However, in various embodiments, discovery protocols may be implemented using a Bluetooth® serial port, RS-232, or may be sent entirely over datagrams or a Windows® Socket API (“WSA”). The LocalClient in the illustrated embodiment may be a new instance of an IDiscoveredClient (defined in FIG. 5) class filled in with the device's identifying characteristics, such as device name, user name, preview image, and endpoint (in this case an IP address and port). First device 110 may open a new socket for a broadcast message (410). First device 110 may transmit the IP address that first device 110 is listening on for a response to the broadcast message (420). First device 110 may open a new datagram socket to listen for a response message (430). After receiving a response message, first device 110 may decipher the response message into the original IDiscoveredClient message that first device 110 sent (440).

Referring to FIG. 5, a definition for an example discovery protocol 500 is illustrated according to various embodiments. The definition may be a single common class called IDiscoveredClient that may be implemented by a transmitting device and a receiving device. In various embodiments, the definition may be expanded to include custom fields and any other information that users may desire. In various embodiments, the definition may comprise a name of the device (510), an IP address of the device (520), an owner of the device (530), and endpoint of the device (540), and a transport layer on which the device was discovered (550). However, one skilled in the art will appreciate that the particular fields used may be altered to any desired fields.

Referring to FIG. 6, a definition for an example file transfer request protocol 600 is illustrated according to various embodiments. The definition may be called “IFileTransferRequest.” In various embodiments, the definition may comprise the name of the device transmitting a file (610), the filename to be sent (620), the size of the file (630), the device receiving the file (640), a unique identification for the file transfer (650), and the transport layer associated with the file transfer (660).

Referring to FIG. 7, a definition for a response to a file transfer request 700 is illustrated according to various embodiments. The receiving device may respond with a definition called IFileTransferResponse to indicate that the receiving device is willing to accept the file transfer. In various embodiments, IFileTransferResponse may comprise the response from the user (710) and the unique identification for the file transfer (720). The transmitting device may receive the response from the receiving device, and the transmitting device may proceed to transmit the file to the receiving device. Once a complete file transfer has occurred, the receiving device may transmit a confirmation to the transmitting device (730).

Referring to FIG. 8, a process 800 for editing a message is illustrated according to various embodiments. A first user may wish to send a text message to a second user. The first user may transmit the text message from a first device to a message server (step 810). The message server may store the text message in a message database. The message server may transmit a notification to a second user on a second device. The notification may indicate that the second user has received a new text message. The second device may request new data from the message server (step 820). The message server may transmit all new data pertaining to the second user stored after a last fetch time (step 830). For example, the second device may have fetched data at 11:00 AM. The second device may request new data at 1:00 PM, and the server may transmit all new data stored after 11:00 AM. The new data may include the text message from the first user.

The second device may store the text message in a cache on the second device. Thus, the text message may be stored locally on the second device. The first user may decide to edit the text message. The first user may use the first device, or any other device, to connect to the message server. The first user may indicate that the first user wishes to edit the text message. For example, the user may click on a “delete” button adjacent to the text message to delete the text message, or the user may click on an “edit” button next to the text message, and a cursor may appear to allow the first user to edit the text message.

The user may edit or delete the text message as desired, and the first device may transmit the edited text message to the message server (step 840). The message server may store the edited text message in the message database. The message server may mark the original text message as invalid or deleted, such that devices may no longer be able to access the original text message. The message server may transmit an instruction to the second device to delete the original text message from the cache of the second device (step 850). In various embodiments, the message server may delete the original text message from any device that has saved the original text message. The message server may transmit the edited text message to the second device (step 860). Thus, regardless of whether the second user has previously viewed the original text message on the second device, the edited text message may be displayed in place of the original text message on the second device. In various embodiments, the edited text message may be displayed with a symbol indicating that the edited text message has been edited. However, in various embodiments, the edited text message may be displayed without any indication that the edited text message was edited.

In various embodiments, the first device may transmit a file to the second device via the message server. In various embodiments, the file may be an attachment to a message. Similarly to editing a text message, the first user may edit, delete, or replace the file after the file has been sent to the second user. The message server may replace the original file on the second device with the edited file. The first user may edit or delete any messages or files previously sent to the second user, regardless of which device was used to send or receive the message or file. For example, the first user may use a first smartphone to transmit a message to the second user. The second user may retrieve the message from a second smartphone, as well as from a desktop computer. The first user may edit the text message from a laptop computer. The message server may delete the original message from the first smartphone, the laptop computer, the second smartphone, and the desktop computer. The message server may replace the original message with the edited message on all devices. In various embodiments, the device used to edit the text message may delete the original message from its cache without additional instruction from the message server.

In various embodiments, the first device may edit an original message on a second device without using the message server or any network. The first user may edit the original message on the first device. The first device may discover the second device using any available hardware. The first device may transmit an instruction to the second device to delete the original message from the cache, and the first device may transmit the edited message to the second device. In response to the first device connecting to the message server, the message server may store the edited message and transmit the edited message to all devices having the original message stored in their cache. Conversely, in various embodiments a first device may transmit an original message to a second device directly without using the message server, and the first device may later transmit an edited message to the second device utilizing the message server.

In various embodiments, the methods described herein are implemented using the various particular machines described herein. The methods described herein may be implemented using the below particular machines, and those hereinafter developed, in any suitable combination, as would be appreciated immediately by one skilled in the art. Further, as is unambiguous from this disclosure, the methods described herein may result in various transformations of certain articles.

For the sake of brevity, conventional data networking, application development and other functional aspects of the systems (and components of the individual operating components of the systems) may not be described in detail herein.

Moreover, examples of mobile device communications include texting, email, and mobile applications for smartphones.

The present system or any part(s) or function(s) thereof may be implemented using hardware, software or a combination thereof and may be implemented in one or more computer systems or other processing systems. However, the manipulations performed by embodiments were often referred to in terms, such as matching or selecting, which are commonly associated with mental operations performed by a human operator. No such capability of a human operator is necessary, or desirable in most cases, in any of the operations described herein. Rather, the operations may be machine operations. Useful machines for performing the various embodiments include general purpose digital computers or similar devices.

In fact, in various embodiments, the embodiments are directed toward one or more computer systems capable of carrying out the functionality described herein. The computer system includes one or more processors. The processor is connected to a communication infrastructure (e.g., a communications bus, cross over bar, or network). Various software embodiments are described in terms of this exemplary computer system. After reading this description, it will become apparent to a person skilled in the relevant art(s) how to implement various embodiments using other computer systems and/or architectures. Computer system can include a display interface that forwards graphics, text, and other data from the communication infrastructure (or from a frame buffer not shown) for display on a display unit.

Computer system also includes a main memory, such as for example random access memory (RAM), and may also include a secondary memory. The secondary memory may include, for example, a hard disk drive and/or a removable storage drive, representing a floppy disk drive, a magnetic tape drive, an optical disk drive, etc. The removable storage drive reads from and/or writes to a removable storage unit in a well known manner. Removable storage unit represents a floppy disk, magnetic tape, optical disk, etc. which is read by and written to by removable storage drive. As will be appreciated, the removable storage unit includes a computer usable storage medium having stored therein computer software and/or data.

In various embodiments, secondary memory may include other similar devices for allowing computer programs or other instructions to be loaded into computer system. Such devices may include, for example, a removable storage unit and an interface.
